AD8418WBRZ-RL from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | -IN | input | Negative differential input, connected to the low side of the shunt; the continuous input common-mode range is -2 V to +70 V. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | VREF2 | input | Reference voltage input 2; it is tied internally to the offset node through a resistor and works interchangeably with VREF1 to set the output offset. |
| 4 | NC | unconnected | No connect; do not connect anything to this pin. |
| 5 | OUT | output | Buffered output with an initial gain of 20 V/V; the output swing is 0.015·VS − 0.020 V at RL = 25 kΩ. |
| 6 | VS | power_in | Single supply input, operating range 2.7 V to 5.5 V, with an absolute maximum of 6 V. |
| 7 | VREF1 | input | Reference voltage input 1; it is tied internally to the offset node through a resistor and works interchangeably with VREF2 to set the output offset. |
| 8 | +IN | input | Positive differential input, connected to the high side of the shunt; the continuous input common-mode range is -2 V to +70 V. |
